How we get energy from the power source:
Quick explanation of process: The sun heats up the atmosphere and hot air rises up and other wind comes to replace them.We can use energy in the wind by building the wind turbines and the propellor. Wind makes the propellor turn and that can create the energy.
Inputs and or Resources required for the power: wind
How the Resouces is transformed to produce electricity: It collects kinetic energy.
Cost of the inputs/resources: Small turbines cost $6,000~$22,000.
Where the resource is from
Impact of the resource extraction: less wind
Affects of the power generation on the environment:
Outputs (pollution, waste, byproducts) from the power generation : Only some pollution when building wind turbines.
Impact on animals or habitats: Wild bird's population, bats.
Impact on people: Visual impact, consumes materials on building the wind turbines.
Cost of building the generator:
Time to build the generator: About 120 000 hours
Cost of the energy produced to consumers:
Energy produced per power plant, per year: 94.1 gigawatts
Cost per Kwh: 6~7 cents in New England
The risks: not so much risks.
Risk of an accident, in a percentage
Result of a major accident
Result of a minor accident
Best location for the power plant: Costal area, top of hill, open plains, gaps in mountain. (place where wind is strong)
Disadvantages
-Wind turbines are noisy and often putted on beautiful places because there is more wind.
-Wind turbines are ugly
-They don't produce same amount of wind power.
-Building wind turbines can make pollutions.
-They don't produce enough energy for all people.
Adventages
-Wind power makes no pollutiohn or gas.
-Free and modern technology
-It is interesting!
Additional Information: small turbines last 20 years.
